The present invention' relatesto a device for adjustingfthe openings oi' sciittle yports and the position of thejpane holders thereof.

In the hitherto 'known constructions of scnttle ports it was onlypossible ,to eiiect one adjustment of the opening, thersaid` adjust` ment being always either in a vertical Vorin Athe adjustment in this manner isa drawback `i0 as inmany. cases it Awould be'rusefnl, for theV purpose .of directing theyentilationy to be ableto Vadjust the opening in an inclined direction, i.4 e. tobe able to `pnt the paneholde'r of the port inaninclined position., L i' The present kinvention Ais intended to eliminate the saidldrawback and has for its principaly object the provision fof l a :device which renders it possible to incline thefpane holder of ascnttle portvat any desired angle of inclinationfand which comprises in combination a pane holder .meansj' `for moving said pzanef holder axially; means" lorrotating said pane holder; a singleV longitudinally movable member actuating according to its.

The socket 6 is'adapted to'fit `exactly over i asquare portion-7 carriedby a toothed wheel l8 which turnsupon'ajjournal pivot 9 carriedin.. the stationary frame 10 oAf-thevsciittle port.` f f n The toothed-wheel actua-tes by-lincans teethgll a, ring l12 carryingV teeth 13 which ,the said:manipulatingfmember 2..";.'l"he` said form a :toothed 'threadwhich isf` in -enga L i ment with a .thread -18ofthe ring oitheI pane holder. This 'ring `by' its -rotation upon itself efeotslthe openingofithe Asentt-l'eport parallel toitsclosing'sjoint jand' :operates in known manner. Y y i VParallelto the toothed wheel 8 a toot-hed wheel 14 carried lby xthe hub: of-4V the hand `wheelf27is arrangedQ-This toothed wheel 14 is'in constant engagementL with at'oothed segmentll provided nponaring 16. .Thc'latterv ring'is provided atcertain points withprolie . this last-named tieure.

tion 18 of the ring 19 in which the pane holder' 21 turns upon pivots 20.

T he device for adjusting the inclination of the pane holder consists substantially (as shown diagrammatically in Figs. 1, 2 and 3) in the connection of the ring 16 by means of the toothed segment 15 with the toothed wheel 14, which is arranged on the hub 3; of the hand wheel 2 and is rotatedbythe latter during the adjustment of the pane holder which is effected in the following manner:

The hand wheel being in the position shown in Fig. 4 when turned actuates the toothed wheel 8, which, by means ofthe teeth 11; causes the ring 12 to turn upon itself, which latter through the agency of the thread 13 causes the ring 19 carrying the pane holder to move longitudinally away from its joint 22. lhis manner of operation is known.

After this iii-st operation has been completed thelocking pin 5 is withdrawn from its groove and the hand wheel 2 is then drawn backwards in the direction of the arrow in Fig. 5 into the position shown in During this movement the socket 6 leaves the square portion 7 of the toothed wheel 8 and the socket enters the hub of the wheel 111` which is provided with a recess to receive it. rlChe locking pin 5 then enters the` second groove of the hub of the hand wheel and the said hub is now connected to the wheel 11i.Y In order to adjust the inclination of the ring 19 and the pane holder 21 as desired it is then only neces sary to operate the hand wheel 2 so as to rotate the hub 3 and to transmit a rotary movement through the toothed wheel 14 and thetceth 15 to the ring 16, which latter ring by means of its projections 17 moves the ring 197 the pivots 2O and the pane holder 21 through any desired angle according to the inclination of the scuttle port opening which it is desired to obtain. The closing of the scuttle port is effected by the reverse 0peration, the socket is brought back into position over the square portion of the gear 8 and, when it is actuated; the ring 19 movesV the pane holder 21 longitudinally against its joint 22.

It will be understood that the details of construction may be modified in various ways without departing from the scope'of the invention. V

The teeth 15 may be arranged over the' whole circumference ofthe ringl 16; so as ing said member either in the position for actuating said rst-named means or in the position for actuating said second-named means; substantially as described.
